COURSEDIRECTOR FOR FLIES.

Application ined september 11, 1922. serial no. 587,430.

. To all 'u1/tom t may concern.

Be it known that I, MArrHnw J. KIVLIN,

i a citizen of the United States, residing at Kingsville, in the county of Kleberg and State of Texas, have invented certain new and useful Improvments in Course Directors for Flies, of which thevfollowing is a specification, reference being had to the accompanying drawings.

It has been found that in opening screen doors, there is a draft or suction around the jamb of the door opening, that is to say preceding and following the person passing through the door opening, and this draft or suction causes iies to take a corresponding course. This being the case, the'present invention has for its purpose the provision of a course director adapted for application upon and adjacent the jarnb of the door opening, that is to say adjacent where the screen door opens, so that when the draft or suction draws or causes the flies to follow the course of the suction or draft, the director or guide will act to govern the course of the iies and keep them from passing through the door opening.

Another purpose is the provision of a director or guide comprising a frame con` sisting of a plurality of pieces connected by a plurality of perpendicular strips, there being a screen covering over the frame, act` ing to prevent the ffies from passing through the door opening.V

Another purpose is to provide a frame which may be constructed of metal as well as of wood, and in this case the horizontal pieces may be made of sheet metal with lateral anges on the arcuate edges thereof, between which Vand half round pieces, vertical bars and the wire mesh or screen may be secured by ri-vets or other suitable means.

It is to be understood that the particulars herein given are in 11oy way limitative and that while still keepingwithin the scope of the invention, any desired modifications Vof detail and desired proportions may be made in the apparatus according to circurnstances.

The invention comprises further features and combination of parts,as will be herein after set forth, shown in the drawings and claimed.

In Vthe drawings Figure lv is a perspective view showing the course director for flies as applied to the janib of the door;

Figure 2 is a horizontal sectional view on line 2-2 of Figure l;

Figure 3 is an enlarged detail view of the course director, showing thesame constructed of wood;

Figure ais a view similar to Figure 3 showing the course director constructed of metal;

Figure 5 is a sectional view on line 5 5 of Figure et;

Referring to the drawings, l designates the frame of the course director, which comprises a plurality of horizontally arranged pieces 2, which may be any suitable proportions and shape, preferably as shown. In

fact the pieces 2 have arcuate edges 3, which are opposite the straight edges 4. The ends of the pieces 2 have short edges 5, which extend at obtuse angles to the edges 4. These edges 5 are designed for the purpose of holding the course director in proper position relatively to the door jamb, in fact at an acute angle thereto, as shown clearly in Figure 2. Connecting the pieces 2 are vertical strips 6, which are secured in recesses 7 of the arcuate edges of the pieces 2. The frame is covered with suitable wire fabric or mesh work 8, the mesh work conforming to the arcuate edges of the pieces 2, so as to guide or direct the flies away from the door opening. As previously stated it has been found that there is a draft or suction around the door jamb, when opening the screen door, and the flies or mosquitoes in endeavoring to pass through the door, will follow or be drawn into this draft or suction, and therefore pass through the door opening, that is to say preceding the person who passes through the door opening. With the present construction of device as applied to the jainb of the door opening, the fiies when drawn in by this draft or suction will abut againstthe interior ef the arcuate screening or wire mesh work, and thereby be prevented from passing through the door open` ing.

ln Figures e and 5 the frame is constructed of metal. In fact the pieces 2 are made of sheet metal, and have their arcuate edges provided with lateral flanges 10, to which the vertical reinforcing bars ll are riveted or otherwise secured as at l5, and arranged between the bars 1l and pieces 2 is wire fabric or mesh work 12.

The course director for iiies in Figures a and is, identical with the course director in Figures l to 3 inclusive, with the eXcep` tion that the device in Figures 4 and 5 is constructed of metal. TWO forms 0f devices are identical in use, and as previously stated are applied to the door frame With one edge adj acent the edge of the door, in such a v position as to permit the screen door to open,

and yet be able to direct the course of the lWire fabric Wall curved in a direction from the jamb toward the door, and adapted yto stop the iies when endeavoring to follow the suction which is created when opening the door.

v 2. Thecombination with adoor frame including a door jamb, of a course directoicomprising a frame securedV to the exterior face Of the jamb and arranged and disposed at an acute anglethereto, said Jframe having a Wire fabric *covering of arcuate shape curved in a direction from the jamb and toward the edge of the door.

3. The Icombination with' a doo-r frame includin a door jamb, of a course director comprising a frame secured to the exterior face of the jamb and arranged anddisposed at an acute angle thereto, said frame having a Wire 'fabric covering of arcuate shape curved in a direction (from Vthe jamb and toward the edge of the door, said iframe comprising a plurality of horizontally disposed flanged metal pieces, vertically disposed bars secured to theY flanges of and rigidly connecting said pieces so as to secure the wire fabric of the course director to the frame.

4. The combination With a swingingly mounted door and its frame, of a. coursedirector ior flies in stationary relation to said iframe and extendinglaterally from the latter in the direction in which thedoor nieves when opening, said course director including arscreen extending from top to bottom of the door. y y

5; The lcombination VWith a sivingingly mounted door and its iframe7 of a course director for iiies in stationary relation tofsaid frame and extending laterally from the latter in the direction in which the door moves when opening, said course Vdirector ineluding a screen extending from top to bottom of the door and being of arcuate form in cross section with the curvature of the same extending toward the door. i
